ABSTRACT
PURPOSE: We investigate the outcomes of treatment of patients with severe comminuted distal radius fractures with volar plate fixation using a pronator-preserving approach. MATERIALS AND METHODS: Fourteen patients with severe comminution of the distal radius fractures for whom anatomical reduction of the fractures was deemed difficult to achieve with traditional approaches were enrolled. The gender ratio was 8 males to 6 females, and the average age of the patients was 64.9 years. According to the AO/OTA classification of fractures, 2 patients had 23-A3 fractures, 7 patients had 23-C2, and 5 patients had 23-C3. Radial length, radial inclination, and volar tilt were measured for radiologic evaluation. Modified Mayo wrist score (MMWS) was used for clinical outcome. RESULTS: Bony union was achieved in all 14 patients without signs of complications. The average time-to-union was 4.3 months (3-6 months). The radiological findings at the final follow-up were as follows: the average radial inclination was 20.5degrees; the average volar tilt, 7.57degrees; and the average radial length, 11.8 mm. At the final follow-up, the results of the MMWS were 'Fair' in 1 patient, 'Good' in 4, and 'Excellent' in 9. CONCLUSION: We propose that a pronator-preserving approach is an effective treatment for severe comminuted distal radius fracture.
